Offline Mobile App Locking Up

(1) ShareShare
ReportReport
Posted on by 5,325 Super User 2025 Season 2
I have built an 'Offline' mobile app that is working inconsistently.

Below is a snapshot of a portion of the app.



The issue, the 'Add Activity' button works sometimes and other times it doesn't.

The button is a navigation button with the following formula -
 
Navigate(Activity_Screen,ScreenTransition.Cover);
 
If(IsBlank(Activity_Quantity_Fld.Text),
Collect(colBillableUnits, {intID: GUID(), rem:false}));

Below is a section of the 'Activity Screen', a gallery.


It is unclear to me why the function of this button is inconsistent.

I have attempted to 'Clear Cache' in the Power Apps player. I have removed
and reinstalled the player; however, the issue keeps occurring.

Is this a device (cell phone, using both an iPhone 15 and a Samsung),
memory issue, a glitch in the Power Apps player?

When it all works, it works great. However, during testing of more than one
project entry this button - and eventually other button stop functioning.

What am I missing?

    Hi
     
    Why are you attempting to do an If and Clear AFTER your navigate. I would suspect it to act weird honestly.
     
    Can you move those steps above the Navigate please and verify that it stops.

    BTW if you are adding that data to the Collection so the Next Screen has it, instead of using globals, (if its the case)
    Simply pass it as a context variable like so

    Navigate(MyScreen, Transition.Whatever,  { _MyData: EnterDataHere } );
     
    Thanks,
